Nicki Minaj And Ariana Grande Bump Booties As They Take The Stage In Typically Revealing Outfits At iHeartRadio

They both have a reputation for diva-like tendencies.

But the stage was just about big enough for both Ariana Grande and Nicki Minaj on Friday night as they performed together at the iHeartRadio Music Festival.

Dressed up to the nines, the twosome bumped booties and happily danced opposite each other as they performed their hit single Bang Bang, without Jessie J.

Ariana sported her favourite over-the-knee boots teamed with a black flared mini skirt, matching crop top and cats' ears headgear for the show.

Nicki was only a little more demure in a pair of ornately decorated leggings, gold and black belt and black and gold bra plunging bra top which left little to the imagination.

She wore her hair long and dark with bright pink lipstick completing the look.

The singers continued with their flirtatious display as they moved around the stage, belting out the tune while raising their arms in the air high above their heads.

At one point, Ariana followed Nicki's lead as the older entertainer danced around for the audience.

Nicki - who also performed her hit Anaconda and an a capella version of Flawless Remix - no doubt had jaws dropping when she sat on a chair and did the splits.

Backstage, Nicki appeared to be in a cheerful mood as she mingled with her Anaconda music video choreographer Casper Smart.

Nicki ran her hand through her long hair while Casper - Jennifer Lopez's ex - sported a Mohawk hairstyle with buzzed sides.
